<div>
  Specify a folder containing a repository that will be used by Git as a reference during clone operations.<br/>
  This option will be ignored if the folder is not available on the controller or agent where the clone is being executed.<br/>
  To prepare a reference folder with multiple subprojects, create a bare git repository and add all the remote urls then perform a fetch:<br/>
  <pre>
  git init --bare
  git remote add SubProject1 https://gitrepo.com/subproject1
  git remote add SubProject2 https://gitrepo.com/subproject2
  git fetch --all
  </pre>
</div>
